Silver pennies are used to buy rewards after Dimension of Disaster, in Gypsy Aris' Reward Shop. Upon the first completion of the quest 10 silver pennies are awarded, and 5 are awarded for subsequent completions. Speak to Gypsy Aris in her tent near Varrock Square to exchange them for rewards.
In order to obtain every reward, excluding the XP lamp, 30 silver pennies are required. Thus, the entire quest must be replayed four times for every reward. Buying all the rewards, excluding the XP lamp, is a requirement for the master quest cape. To obtain all the rewards, including the XP lamp, 35 silver pennies are required requiring a total of five replays.
- Silver pennies are the currency used in Bree in The Lord of the Rings.
